I'd like to copy files and ensure the file is copied accurately (is exactly
the same). Is there ai way to set WinXP to do a CRC of teh source and copied
file to ensure they really truly match?

Sure you can do it from command prompt.
Before issuing copy command, give following command
VERIFY ON.
This will set verify parameter ON
And for that particular session after every copy, original and new
files will be compared.
Works only from command propmt though

VERIFY ON and XCOPY/COPY /V options do not do a bitwise compare. They only
verify the written file is readable.

FC does a bitwiise compare as does a folder compare tool that's on some
Windows CDs; but I need a tool that copies and compares in one operation.

The third party program XXCOPY comes close, but you must manually invoke the
CRC compare as a second step after the copy has completed. I don't want to
be there - copying 250GB is an all night affair and I want it done when I
come back in the morning.

xxcopy should not only suffice well for that purpose,
it's much faster than a GUI interface and won't take
near as long as you expect. Just write a batchfile
with the xxcopy commands you need.
